提出了柔性桩隔震消能主动控制体系，建立了体系的动力分析模型，推导了其振动和控制方程。以一典型的柔性桩隔震消能结构为例，分析研究了其隔震性能及控制效果以及各主要参数对控制效果的影响。研究结果表明：柔性桩隔震消能体系能有效减小结构的地震力响应；对柔性桩消能隔震体系施加主动控制，可以有效降低桩顶与套管壁之间碰撞的可能性，同时，结构上部竖向荷载、上部结构刚度及桩长等对结构的控制效果有显著的影响。

Abstract: the flexible pile isolation to active control system is proposed , the system of dynamic analysis model is established, and its vibration and control equations are derived. In a typical flexible pile base-isolated structure, for example, to study the isolation performance and control effect and the main parameters of control effect. Research results show that: the flexible pile isolation system can effectively reduce dissipation structure of the earthquake response, Flexible pile of base-isolation system with active control can effectively reduce the pile cap with the possibility of collision between the casing wall, at the same time, the vertical load the of structure, the upper structure stiffness and the length of the pile have significant influence on the control effect of the structure.
